OUAI Fine to Medium Hair Treatment Mask (3.4 oz) — Weightless Hydration & Frizz Control

This treatment mask combines nourishing butters and targeted proteins to refresh dry, damaged strands while keeping hair buoyant and soft. Formulated for finer textures, it restores moisture, smooths cuticles, and helps reduce breakage after color, heat styling, or everyday wear. The 3.4 oz size is ideal for trying the formula or keeping on-the-go for quick weekly treatments.

How does this mask give weightless hydration?

The formula blends rich emollients and lightweight humectants so hair gets lasting moisture without feeling heavy. Ingredients work at the fiber level to smooth and replenish, yet rinse away clean for natural movement.

• Shea butter delivers deep conditioning while being balanced for fine strands.
• Panthenol attracts and holds moisture to maintain softness and elasticity.
• Hydrolyzed keratin reinforces weakened areas to reduce limpness from damage.

Will this help tame frizz and split ends?

The treatment helps manage surface irregularities that cause frizz and the sensation of split ends, improving texture and gloss. Regular use can make hair feel smoother and easier to style, though it does not remove split ends permanently.

• Seals the cuticle to reduce roughness and flyaways.
• Adds shine to improve the appearance of damaged ends.
• Strengthening proteins help prevent new breakage from styling stress.

How do I use it for best results?

Apply to clean, damp hair after shampooing. Work a small amount from mid-lengths to ends, leave for a brief treatment time, then rinse with cool water to help smooth the cuticle and lock in shine.

• Squeeze excess water from hair before application for even coverage.
• Start with a quarter-size amount; adjust if hair is longer or drier.
• Five minutes is typically sufficient; rinse thoroughly with cool water.

What does it smell like and what are the ingredient highlights?

The scent, Melrose Place, layers rose with bergamot, lychee, white musk, and a subtle sparkle of champagne for a modern floral-fruity aroma. Key actives center on conditioning and repair to improve manageability and resilience.

• Shea butter — rich hydration and softness without excess weight.
• Panthenol — moisture retention and improved hair pliability.
• Hydrolyzed keratin — peptide support that helps reduce breakage.
